Hello, my name is Leah. I randomly came across your post while doing a search on google. For years i have been having troubles with my heart. Extreme palputations, pounding to the extent of my shirt moving, ect. Lately, it has been getting worse, at an increased rate. I have begun to lose sleep due to my heart pounding so hard i cannot rest. My roommate is a medical student and i was explaining to him how my heart has always bothered me but has been incresingly worse lately. He started to do a search online about the few symptoms i had given him then asked me a load of other questions about the symptoms you listed above then said that this is what he thought i had. I have all these symptoms but i didnt ever think they were liked or related to each other. But seeing this list worries me bc im deeply afraid that i may have a tumor as well. Im a 21 yr old female and im just beinging to research this so i dont know alot about it. But if there is any useful info or something to calm my nerves then PLEASE feel free to email me. My email is leah.kipp@yahoo.com. I really dont know how to use this curezone thing.... i just signed up to leave a comment in response to your post. So if you could email me on my personal email, i would really like to hear from you. Thank you so much and i hope all goes well with your future doctor appointments!
